American scientist sells Nobel prize for $4.5 million

According to the BBC, the medal was expected to be sold for $2.5 million $3.5 million at Christie's auction house in New York. This is the first Nobel Prize medal to be sold by a living recipient. It has been said that Watson, 86, put his medal up for sale because of financial difficulties.

It was reported that Watson will donate part of the proceeds from the auction to Chicago University where he studied, Cambridge University where he worked and to Cold Spring Harbor Laboratory where he worked as chancellor.

It was claimed that Watson was excluded from the scientific community after his statement that "black people are not as intelligent as whites," which he suggested in an interview in 2007.

Watson received the Nobel Prize for medicine for the discovery of the double helix structure of DNA, along with Francis Crick and Maurice Wilkins. Crick passed away in 2004 and his medal was sold for $2.2 million last year.
